About this part

Product Details

Grams Performance is known for making high-performance fuel injectors for demanding vehicles. If you're looking to upgrade the fuel system on your 1990-1997 or 1999-2005 Mazda Miata, this 1150cc injector kit is a solid choice. These injectors are crucial for accurately delivering and atomizing fuel, especially when you've modified your engine for more power.

This kit features injectors with stainless steel internals that can handle all types of fuels, including oxygenated ones like FTW, Q16, M5, and C45. Grams Performance tests each injector individually to ensure it flows within one percent of the others in the set. This precise matching means you get consistent cylinder-to-cylinder performance, which helps maintain a smooth idle, improves throttle response, and maximizes overall engine performance, even with very short fuel pulse widths. The solenoids are designed for ultra-fast and precise operation, maintaining a linear fuel delivery across a wide range of operating conditions and fuel pressures.

This set includes four 1150cc injectors, each with an 11mm top adapter and a black bottom adapter. You'll need to splice wires for installation, but they are designed to be plug-and-play with a fuel rail spacer. Please note that these injectors are not CARB approved and cannot be shipped to California.
